Physical Features of Water and Surface Sediments in the Ha Long Bay, Viet Nam

Ha Long Bay's water and surface sediments exhibit conditions that support sustainable aquatic ecosystems, with water quality generally meeting Vietnamese aquaculture standards. The bay's sediments range from sand to silt, dominated by silt, and display light alkaline-reduced environments (pH and Eh values). Key minerals identified include quartz, kaolinite, illite, calcite, and goethite. Water parameters like salinity, turbidity, and total suspended solids (TSS) vary seasonally due to mainland influences, particularly during dry and rainy seasons. This study provides a comprehensive analysis of the bay's physical features, highlighting their ecological significance.
